Carrot, also known as yellow radish, is a kind of nutritious and good vegetable suitable for all ages, and is known as "Little Ginseng". The most famous component in carrots is carotene, a yellow pigment, which was first discovered in carrots more than 0/00 years ago. It is now known that carrots contain carotene1.35 ~17.25mg per 100g, which is far more than other vegetables, 360 times that of potatoes and 36 times that of celery. Carotene can be converted into vitamin A after it enters the human body and is absorbed, so it is also called provitamin A. What is valuable is that although carrots are cooked and steamed in the sun, the loss of carotene is very small. Eating carrots regularly has many benefits to the body: first, it can enhance immunity, fight cancer and prevent diseases. For example, the lack of vitamin A in human body not only has great influence on eyes and skin, but also has poor resistance, which is prone to respiratory and urinary diseases. If you eat carrots regularly to meet the human body's demand for vitamin A, it can not only nourish the eyes and mucous membranes, but also enhance the human body's disease resistance. In addition, carrots contain a lot of lignin, which can also improve the body's disease resistance and reduce and prevent cancer. According to the observation of British and American cancer research institutions for more than 20 years, people who often eat foods rich in vitamin A, such as carrots, are 40% less likely to develop lung cancer than those who don't often eat such foods. The second is beauty and fitness. Another function of vitamin A is to maintain the normal function of human epithelial tissue and make it secrete glycoprotein to keep the skin moist and tender, so eating carrots often can keep a radiant young image. In addition, carrots contain mustard oil and amylase, which can promote the metabolism of fat, prevent excessive fat from accumulating under the skin and getting fat, and keep fit. So Americans think carrots are beauty dishes, which can nourish hair, skin and mucous membranes.
